What is the lowest temperature geraniums can tolerate?
Considering this, can geraniums survive a freeze?
Elsewhere, grow them as outdoor annuals or indoor houseplants. While geraniums can withstand cooler temperatures and even light frosts, hard killing freezes -- when temperatures drop below 20 degrees Fahrenheit -- result in freeze damage and possibly death of the geranium.
Furthermore, what temperature is too low for geraniums? During winter, geraniums grow best with night temperatures of 50° to 60°F (10° to 16°C) but will survive if they drop to 32°F (0°C) and/or rise above 80°F (27°C), as long as they are kept relatively dry.
Also know, what is the lowest temperature petunias can tolerate?
(16 to 18 C.). However, petunias usually tolerate temperatures as low as 39 F. (4 C.) with no problem, but they are definitely not plants that will survive the winter in most climates.
Is it too early to put out geraniums?
USDA Zones 9 and Below To grow perennial geraniums in one of these cooler USDA zones, plant your geraniums in a container that may be moved indoors in mid- to late fall, before the first frost. Geraniums may be brought outdoors again in the early to midspring, when the threat of frost has passed.
